The 25-year-old actor also shared that he thinks young Disney Channel stars should receive counseling from the network.
Gregg Sulkin and Bella Thorne may no longer be dating, but he'll always be there for her.
ET's Katie Krause sat down with Sulkin during a Facebook Live interview on Tuesday, where he opened up about supporting Thorne after her emotional abuse revelation.
"I spoke to her. She's good," he said of Thorne, who claimed on Sunday that she was sexually abused until age 14. "You saw at the Golden Globes this week how important it is for certain messages to be put out into the universe."
"For anybody that has ever experienced that kind of thing, they do have a voice," he said. "It must be extremely difficult and hard to try to share their story, [but] the more stories that are shared, hopefully the less it will happen."
The 25-year-old actor, who, like Thorne, came from a Disney background with his role opposite Selena Gomez on Wizards of Waverly Place, also opened up about the stresses of being a young TV star, and said that he thinks Disney should offer counseling to their actors.
"It is hard to remain levelheaded, so I do believe that there should be like, once a week, on any young network, there should be somebody that comes in and talks to these young actors about their life and hearing their teenage thoughts," explained Sulkin, who now stars on Marvel's Runaways. "I think it's hard... when you don't realize you're becoming, like, a multimillion-dollar business."
"One day, if I continue to work, one thing I want to do with my voice, so to speak, is to make sure that younger actors don't end up going down the path of some actors that we've seen throughout the years," he continued. "Exactly like the conversation with harassment... [it] would be a nice way to just, kind of, encourage kids to support each other and have a voice."
"I'm surprised [Disney doesn't already do that]," he added.
As for Gomez, Sulkin said he's happy to have seen her flourish into "one of the biggest superstars in the world."
"I'm happy it's happened to a nice person, because a lot of people in this industry, you seem a certain way, and maybe aren't. But she's always been really lovely, has always been very determined, hard-working, and if you type in like, 'Selena Gomez scandal,' on Google, you'll never find one," he shared, adding that he could see the Wizards cast reuniting on screen in 10 to 15 years.
"I mean, that show gave me my start here, so I'll always be grateful, and I'll always want to do a reunion," he expressed, noting that "it's gotta make sense on a career level for every single person involved."
The season finale of Marvel's Runaways is now streaming on Hulu.
